4-Chloro-4'-hydroxybenzophenone

CAS: 42019-78-3

4-Chloro-4'-hydroxybenzophenone is a chemical intermediate that is used to produce p-hydroxybenzoic acid by acylation reaction with hydrochloric acid. The optimal reaction of 4-chloro-4'-hydroxybenzophenone with hydrochloric acid occurs at a temperature of 40 degrees Celsius and an excess of 2 equivalents of hydrochloric acid per equivalent of 4-chloro-4'-hydroxybenzophenone. This chemical intermediate has been shown to be an environmental pollutant, as it reacts in the atmosphere with ozone or other oxidizing agents to form hydrogen chloride and aluminium chloride. The transfer mechanism for this process is not yet well understood, but it may be due to demethylation followed by chlorination.
